Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613698, here are decompositions:

29 + 31613669 = 31613698
59 + 31613639 = 31613698
71 + 31613627 = 31613698
257 + 31613441 = 31613698
449 + 31613249 = 31613698
971 + 31612727 = 31613698
1031 + 31612667 = 31613698
1109 + 31612589 = 31613698

Showing the first eight; more decompositions exist.
